SPECIFICATION forming part of Letters Patent No. 504,466, dated-September 5, 1893. Application filed December 8, 1892. 4 Serial No. 454,479- (No model.)

To all whom it may concern,.-

Beit known that I, JAMES C. BENSON, a citizen of the United States, and a resident of Alcony, in the county of Miami and State of Ohi'o, have invented certain new and useful Improvements in Grain-Separators; and I do declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form apart of this specification.

Figure l of the drawings isa side elevation.' Fig. 2 is a vertical longitudinal section. Figs.`

3 and 4 are detail views, and Fig. 5 is a detail view of the lower shoe in cross section.

This invention has relation to certain new and useful improvements in grain cleaners, and it consists in the novel construction and combination of parts, all as hereinafter described and pointed out in the accompanying claims.

Referring to the accompanying drawings, the letter A designates the frame of the mill or cleaner, having supported thereon a hop per B. Y

C designates the upper or 'chatting shoe, carrying the screen D, and the grain board D extending underneath said screen .to a point near the rear end thereof. The frame E of said shoe forms an integral part of the casing E', and the blast chamber case or drum E2, as shown, said casing, drum and shoebeing supported by the rollers a, a, carried by the legs or standards b, b, and by the bars or links F, F', one of which is connected at its upper end to each side of the rear portion of the upper shoe, and at its lower end. to the upper portion of the lower or grading shoe G, the intermediate portions of said bars or links working loosely on pivot studs or journals e, carried by irons d afixed to and projecting from the legs or standards e', e.

Secured to the outer face of each standard or leg b, is a bar or strap H, the upper portion of which is formed with an elongated vertical slot f, said slot engaging a crank pin f on the respective ends of the fan shaft H. The pin f at one end of the shaft H is carried by a small pinion Hzon said shaft which pin is engaged by the driving gear wheel H3, and

drives said shaft and fan. In the lower porof holes g, any one of which is designed to be engaged by a pin or stud on a bar I, which at its opposite portion is secured to the casing E. The bar I is secured to the casing by means of a bracket plate E2, (Fig. 3), having an integral pivot stud e which engages the end of said bar. Similar bracket plates may also be used for connecting the bars or links F, F', to the casing. It will be apparent that when the blast wheel or fan is revolved, through this connection a vibratory reciprocating motion will be imparted to the upper shoe, which movementwill be communicated oppositely to theV lowershoe through the bars or links F, Ff; alsothat by varying the point of connection at g,`this movement may be regulated to suit the character ofthe grain being operated upon. The lower shoe which extends the entire length of the frame,

is provided with usual arrangement of grad- 4which projects through the casing and works in an arcuate slot j therein.

K is a notched curved bar, or segment rack, pivoted to the outer face of the casing, and

so arranged that its notches or teeth will engage and support the stud or pin fi, thus providing for different adjustments of the board J, to suit the grain being cleaned, and to direct the chaff into the chaff chute J', which discharges at one side.

L is a second and similar board, which is hinged at the opposite side of the graiupassage from the board J, and which is inclined oppositely to the board J. This board isprovided with means for its adjustment similar to those for the board J. Said boards J andL also act in conjunction with a third board M which is hung in the blast chute O, and is adjusted in the same manner, to regulate the direction and character of the blast.

tion of each of said bars or straps is a series Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a grain cleaner, the combination with the upper or chatting shoe, the casing, and the drum, all in one frame and movable to- `gether, of the fan shaft, having the crank pins thereon, the bars or straps H, H, one on each side and secured to the legs or standards at their lower portions, their upper portions having each an elongated slot engaging said pins, the bars I, one on each side and adjustably connected at one end to said bars H, and at the other end affixed to the said casing, the lower shoe, and the pivoted links or bars connecting said lower shoe with the upper shoe, substantially as specified.

2. In a grain cleaner, the combination with the lower shoe, the hopper having the grain discharge, and the fan, of the transverse grain boards J and L, one situated on each side of the grain passage underneath the hopper, and inclined oppositely to each other, the wind board M operated in connection with said grain boards, and means for eeoting and securing the independent adjustment of each of said boards,substantially as specified.

3. In a grain cleaner, the combination with the hopper and the grain passage therefrom, of the transverse pivoted boards J and L, situated one upon each side of said passage, underneath the hopper, means for effecting and securing the independent adjustment of each of said boards, and a cha chute in front of and below the board L, said chai discharging at one side, substantially as specied.

In testimony whereof Iaix my signature in presence of two witnesses.
